NAME
explain_strndup_or_die - duplicate a string and report errors
SYNOPSIS
#include <libexplain/strndup.h>
char *explain_strndup_or_die(const char *data, size_t data_size);
char *explain_strndup_on_error(const char *data, size_t data_size);
DESCRIPTION
The explain_strndup_or_die function is used to call the strndup(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_strndup(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The explain_strndup_on_error function is used to call the strndup(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_strndup(3) function, but still returns to the
caller.
data The data, exactly as to be passed to the strndup(3) system
call.
data_size
The data_size, exactly as to be passed to the strndup(3) system
call.
RETURN VALUE
The explain_strndup_or_die function only returns on success, see
strndup(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_strndup_on_error function always returns the value return
by the wrapped strndup(3) system call.
EXAMPLE
The explain_strndup_or_die function is intended to be used in a fashion
similar to the following example:
char *result = explain_strndup_or_die(data, data_size);
